Make all right, but when I double click modified .pkg I cann`t install in any HDD.
Sorry my English is very bad.
Ok, maybe images will help?
1: Download OS 10.12.2 from Apple
here.
2: Open the downloaded .dmg (I downloaded macosupd10.12.2.dmg). I moved mine to the Desktop first.
3: Unpack .pkg in terminal (pkgutil --expand /source /destination). In this case, I unpacked the file from my Desktop to a folder called "Modified Installer" on my Desktop. NOTE: I have edited out my username so your terminal window will have your user name where there are large blank spaces in the attached screen shot.

4: Look up your Mac model's "boardID"
here. Copy the boardID.
5: Inside the "Modified Installer" folder, open the "Distribution" file with text edit. Add the boardID inside the bracket after "var boardIds = ". Be sure to use straight ' and not ’.

6: In the "Distribution" file, scroll down to "var nonSupportedModels =" and remove your Mac's model from the list.

7: Save the modified "Distribution" file.
8: Flatten the modified pkg in terminal (pkgutil --flatten /modified_source /destination). In this case, I flattened the "Modified Installer" folder on my Desktop to a .pkg named "Install 10.12.2.pkg" on my Desktop. This step may take a minute or two so wait until complete (the command prompt will return and the red close window button will not have a black dot).

9: Double click your modified .pkg and run the installer normally. If you did not follow directions, you will get error because "Distribution" file checks your machine as not supported. Go back to step 4 and try again.

The unmodified installer will not run on unsupported machines. But yeah, it is a good place to download updates if foxlet's AUS server isn't doing the job for you. If you have multiple machines you could consider making your own patched updater .pkg as
I described above.
